Collected the pannier rails Friday at long last and fit them Saturday. I had to take a mallet and an angle grinder to the left pannier mounting bracket

but other than that it all went together well enough. Erm, other than the battle I had refitting the stop light . . . . . . . and the fact that I cross wired the indicators!

The quick locks mean the rails can be released for removal in seconds. The cross brace however, requires the removal of four bolts. I intend to see if I can make the cross brace installation/removal a bit slicker. I reckon it should be possible to install or remove luggage and rails in less than 30 seconds.
One pics shows the bike fully loaded. The other with luggage and rails removed.
